According to MiningWeekly, according to the latest statistics released by the International Copper Research Team (ICSG), the output of world's copper mines fell by 2.6% year-on-year in the first 10 months of 2017, with the output of concentrate copper dropping by 2.2% and that of solvent extraction-copper electrode dropping by 4.3 %.

Regionally, copper production in the African mines fell 1%, in the Americas 3%, in Asia 4%, in Oceania 3%, but in Europe (including Russia) by 2%.

Copper production in Chile, the world's largest copper producer, fell 2% due to a strike at the Escondida mine and a decline in production at National Copper Company.
